RandomUtil
Overview
The RandomUtil
module, accessible as an NPM package in both amd
and commonjs
configurations, expedites the prototyping of web interfaces. It adeptly fills DOM
elements with a variety of random content. The module's versatility extends to numerous data types, encompassing text (encompassing titles, tags, and excerpts), images, tailored dates, and SVG-crafted avatars.

Module Example
import RandomUtil from "@danielhaim/randomutil";
const randomContentManager = new RandomUtil.RandomContentManager(1);

count: imageCount,
query: "nature",
orientation: "portrait",

Browser Example
<script src="./path/to/dist/randomutil.amd.js"></script>
<script>
const randomContent = new window.RandomUtil.RandomContentManager(1);
const randomController = new window.RandomUtil.RandomUtilController();
</script>
RandomContentManager()
- The
RandomContentManager()
manages content distribution from a set of five arrays, while RandomUtil.Controller()
handles the distribution of this content. Each array focuses on distinct themes
Array 1
: Wildlife preservation and conservation content.Array 2
: Global explorations and adventures.Array 3
: Technology and innovation topics.Array 4
: Fashion and beauty-related content.Array 5
: Creative and advertising materials.
const randomContent = new RandomContentManager(3);
const randomController = new RandomUtil.Controller();
randomController.generateTag(randomContentManager.tags);
randomController.generateTitle(randomContentManager.titles);
randomController.generateExcerpt(randomContentManager.excerpts);
RandomUtil.Controller()
The RandomUtil.Controller()
is in charge of content distribution and offers several methods to target specific DOM
elements:
Method | Target Element | Output |
---|
randomTitles(titles) | [data-random="title"] | Randomly selects and populates title elements. |
randomTags(tags) | [data-random="tag"] | Assigns random tags to elements. |
randomExcerpts(excerpts) | [data-random="excerpt"] | Fills elements with random excerpts. |
randomReadTime(text = 'min read') | [data-random="read-time"] | Generates read time content (e.g., "8 min read"). |
randomDate(format) | [data-random="date"] | Provides random dates in the specified format (default: M j, Y , e.g., Dec 21, 2019). |
randomDate | [data-random-date="l, F jS, Y"] | Custom date format support (e.g., "Saturday, December 21st, 2019"). |
randomColors({ options }) | [data-random="color"] | Adds custom CSS variables with hex, rgb. |
randomImages({ count, query, orientation, accessKey }) | [data-random="img"] | Fetches random images (requires Unsplash API Key). |
randomImages({}) | [data-random-img="person, face"] | Advanced image querying for specific elements. |
randomAvatar({ avatarOptions }) | [data-random="avatar"] | Provides random avatars with options like 'pixel', 'smile', or 'abstract'. |
randomAvatar({ avatarOptions }) | [data-random-avatar="pixel"] | More advanced avatar customization. |
const randomContent = new RandomContentManager(1);
const randomController = new RandomUtil.Controller();
randomController.randomTag(randomContent.randomTags);
randomController.randomTitle(randomContent.randomTitles);
randomController.randomExcerpt(randomContent.randomExcerpts);
randomController.randomReadTime();
randomController.randomDate("Y/m/d");
const randomImageCount = document.querySelectorAll("[data-random='img']").length;
randomController.randomImages({
count: randomImageCount,
query: "nature",
orientation: "portrait",
accessKey: UNSPLASH_ACCESS_KEY
});
randomController.randomAvatar({
avatarOptions: {
colors: ["#FF5733", "#33FF57", "#5733FF"],
variant: "default"
}
});
randomColor({ options });
Dynamically apply a random color to elements specified by the [data-random="color"]
attribute. It allows for selecting colors from a predefined palette or a custom set of colors, further offering the ability to customize the CSS variable names used for the RGB and hex color values.
const randomController = new RandomUtil.Controller();
randomController.randomColor();
randomController.randomColor({
customColors: [
"#405de6",
"#5851db",
"#833ab4",
]
});
randomController.randomColor({
varName: 'primary',
customColors: [
"#405de6",
"#5851db",
"#833ab4",
"#c13584"
]
});
randomDate()
The randomDate()
method is designed to populate elements with [data-random="date"]
and [data-random-date=""]
attributes. Utilizing the [data-random-date]
attribute, you gain access to more specific date formats, such as l, F jS, Y
, which results in a formatted date like "Saturday, December 21st, 2019." This flexibility allows you to tailor the date presentation to your specific needs.

randomImages()
This method allows you to fetch images from the Unsplash API. To get started, you can register an Unsplash Application and grab your access key here.
- The
randomImages({ count, query, orientation, accessKey })
constructor: count
(Optional): Number of images to fetch. Default is 12.query
(Optional): The category of images. Default is "nature".orientation
(Optional): The orientation of the images. Default is "landscape".accessKey
(Optional): Your Unsplash API key. If not provided, it will default to process.env.UNSPLASH_ACCESS_KEY.
const UNSPLASH_ACCESS_KEY = 'your-api-key';
const randomController = new RandomUtil.Controller();
const randomImageCount = document.querySelectorAll("[data-random='img']").length;
randomController.randomImages({
count: randomImageCount,
query: "nature",
orientation: "portrait",
accessKey: UNSPLASH_ACCESS_KEY
});
<img data-random="img" />
<img data-random="img" data-random-img="person, face" />
<img data-random="img" data-random-img="school bus" />
randomAvatar({})
The randomAvatar
method offers the functionality to create diverse and customizable avatars. This implementation draws inspiration from a modified version of Boring Avatars in vanilla JavaScript.
const randomController = new RandomUtil.Controller();
randomController.randomAvatar({
avatarOptions: {
colors: ["#FF5733", "#33FF57", "#5733FF"],
variant: "default"
}
});
